IMPROVEMENT IN BRICK-MACHINES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that we, BENJAMIN' M.-GARD, of Urbana, in the county of Champaign, and State of Ohio,

i and EMEnY R. GARD, ot' Chicago, in the county of Cook, and State of Illinois, have invented cert-'ain new and useful Improvements in Machines for Making Figure l represents a perspective view of the machine, with a part of the clay-hopper broken away to show the interior.

Figure 2 represents a vertical section through the machine.

Figure 3`represents a horizontal section through the clay-hopper, and showing a top plan of the tub and mold-wheel.

Figure 4 represents in perspective and separated from the machine, the cam-trough track for raising, lowering, and adjusting the followers that work in the molds.

Similar letters of reference where they occur in the separate figures denote like parts of the machine in all of the drawings.

The object and purpose of our invention is to cheapen and simplify a brickpress, and to bring it -within rery restricted limits o r space without impairing its eiciency. And this we accomplish hy a construction and arrangement of the several working parts of the press around a central shaft, through which the whole machine is driven and worked, thus dispensing with gearing, and much of the expensive parts of brick-machines that are driven by gearing, and bringing the whole machine within an exceedingly contracted space.

To enable others skilled in the art to make and use our invention, we will proceed to describe the same with lreference to the drawings.

In a stout substantial frame, A, is supported a shaft, B, which may be turned by a sweep, C, the aim D of which is made adj ust ble by a screw-clip or cla-mp, a', upon the sweep, so that the machine may be adapted to one, two, or more horses, as may be deshed.

'Ihe top bearing or support of the shaft B is at l), and the bottom bearing or support at c.

On the base of the main frame A, and around the shaft B,.there is arranged a trough-shaped cam-way, E, which may contain oil for lubricating the stems el of the followers e, as they pass around on'said cam- Iyn or on that portion of the cam-way where the pressure is made that packs the clay in the mold, and as secu at f, there is placed a steel plate, that forms the plane over which the stems 'IZ vof tliepfollowers pass; and that compensation may be made for the wearing of this plate, or to adjust it for varledpressure, a set-screw, g, from below thev cam-plate, comes up against it, and thus can be raisedfor lowered, as may be desired, whilst the'cain-plate itself is station- The mold-wheel F is fast upon the shaft B, and turns with it, and has in it the molds la, in which the followers e work, said followers being plane surfaced,

or rigid, for making plain or tile bricks, as maybe desired. e

lhe tub bottom G has projections H H upon it by which it is supported in the sides of the main frame A. Set-screws ii pass through the arms H, and rest on or in the frame, so that said tub bottom may be leveled or adjusted, when necessary, to adjust it tothe mold-wheel.

One side of the tub bottom, j, is out away, so that the clay may pass down freely to the 'mold-wheel, whilst the opposite sidey of it is elevated, as at k, so as to leave space enough between it and the mold-wheel for the pressedbrick to 'be forced into out of the mold, and for its easy removal by the attendant on the machine.

On the shaft B, and just above the tub bottom G, are placed the screw-blades I I, which force or press the clay into the molds la, and above the'screw-blades on or in the shaft' are knives or mixers J- J, Svc.

K is the tub or hopper, into which the clay isA ofthe invention, as the whole machine' would still be built around a cent-ral line, which may be the axis of the mold-wheel, and the mold-wheel and screw-blades still be on one and the same shaft, and move together.

Having thus fully described our invention,
